Title: Apparatus for feeding vessels to a treatment machine
Inventor: BISCHKOPF REINER
IPC: B67C7/00
Filed: 1989-03-22
Abstract: At the entry of a treatment machine (12) for vessels (11), two conveyor belts (1, 2) frictionally grasping between them the vessels fed by a conveyor band (3) are arranged at a distance in front of the dividing worm (6). These conveyor belts (1, 2) are driven by a motor (5) and a control device (22), to which are connected a signal generator (21) recording the rotational speed of the dividing worm and a monitoring device (4) recording the formation of a closed vessel row in front of the dividing worm. When a closed vessel row of a specific minimum length is located in front of the dividing worm, the conveyor belts are driven at a transport capacity which is 10% lower than the transport capacity of the dividing worm. If the closed vessel row is absent, the transport capacity of the conveyor belts is 10% higher than the transport capacity of the dividing worm. In this way, even highly sensitive, easily deformable vessels made of soft plastic or the like can be fed to the treatment machine with high capacity and without the risk of being crushed in the dividing worm. <IMAGE>
